An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-43764 in the wild and no public exploit code.\n\nAffected product: B\u0026R APROL. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-43764/ (Markdown: https://insights.sbomify.com/CVE-2022-43764/index.md)","id":"CVE-2022-43764","markdown":"https://insights.sbomify.com/CVE-2022-43764/index.md","name":"CVE-2022-43764","record":{"aliases":["GHSA-pmw8-p4g8-wr53"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Automation Server","requires_auth":"none","summary":"A buffer overflow in B\u0026R APROL Tbase Server allows attackers to execute arbitrary code or cause denial of service via malicious configuration inputs.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"industrial_automation_aprol","vendor":"br-automation"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Insufficient validation of input parameters when\nchanging configuration on Tbase server in B\u0026R APROL versions \u003c R 4.2-07 could result in buffer\noverflow.
